Oct. 24, 1944,.' w. C. MAYER Y DRAWER SUPPORT Filed'septyso. 1942 2Sheets-Sheet 2 INVENTOR WILLIAM C .MAYER ATTORNEYS Patented Oct. 24,1944 A UNirso isTitres"` PATENTTOFFICE My invention refers particularlyto anti-frictionv multiple extension supports for `cabinet drawerswherein, broadly, the support'embodies a pair ofsliding rails which aremovable in andfout from the cabinet and when the drawer is open y thesesliding rails form what might be termed a cantilever support, lit beingunderstood that the device as a whole can' be manufactured of wood, toculminate the present war restrictions.

vThe particular object of my invention'is to provide a drawer havingstrips attached thereto, provided with a plurality of roller-engagingiixed and floating -rails whereby, when the drawer .is drawn outwardly,the load is automatically transferred from one pair of anti-'frictionrollers to another pair, whereby 'the load strain :is resisted, it beingunderstood that thel extension'of the rails, form a progressive`movement, limited by inter-lockingpin stop means.

With the above and other minor objects inview the inventionv consists incertain peculiarities Vof construction and arrangement of parts, .aswillbe hereinafter fully set forth in connection'with the accompanyingdrawings .and subsequently claimed.` Y A f Y,

In the drawings: .f

Figure 1 represents a sectional .elevation illustrating a fragment ofacabinet together witha drawer equipped with cantilever slide vsupportsembodying the features of my invention, the, section being indicated byline I-I of Figure 3.-

Figure 2 is a Aplan sectional viewxofithe same, the section beingindicated by line. 2 2 of Figure l.

' Figure 3 is an enlarged cross sectional view of the slide railmechanism, the section being indicated-by line 3-3 of Figure 1.

Figure 4 is'another cross `sectionalelevation of the slide railmechanism, the section being indicated by line 4-4 of Figure 1 in thedirection indicated by the arrows.

Figure 5 is a fragmentary detail sectional elevation illustrating allocking and release mechanism for the drawer, the same being taken upona plan corresponding to Figure 1 with the drawer slides in theirdistended position.

Figure 6 is a similar sectional view wherein the lock and release blockis removed and the drawer is tilted from its normal position forremoval.

Referring by characters to the drawings, I-I indicate the side walls ofa filing cabinet and 2 the back wall; 3 indicates an indirect drawersupporting arrangement forming a bottom wall of the cabinet and 3 asimilar drawer supporting arrangement or wall, it being understood thatthe vApplication September 3.0, 1942, Serial No. 460,255 2' Claims.(01.45-77) cabinet isv provided with a series of suchdivisions (notshown). Secured .to the side walls I is a pair of horizontally disposedfixed trackfrails4, extending from the back wall to a point adjacentthefront or'mouth ofthe cabinet. These fixed rails are shown indove-,tail connection with the side walls I but .obviously any othersuitable means may be employed for securing the same.

r The sides'5 of the drawer have attached thereto horizontally disposedstrips 6, preferably 'counter .sunk into said side walls and positioneddirectly under the strips 4. As best shown in lFigurel of the drawingsthe drawer strips 6 are provided with a pair of lower spacedanti-friction rollers 'I-'I projecting slightly below thelower face vofsaid stripand the same are also provided with rollers 8 positioned inthe rear of said strips, it f .being understood that these rollers aremounted in cavities formed in the strips for convenience inmanufacturing and that said rollers 8 project above 'the top faceof thestrip, adapted to engage the lower faces of the rails 4,` as bestillustrated in Figures l` and 4 of the drawings.

The drawer proper is of standard construction having a front panel 9which fills the mouth of thecabinet cell when the drawer is` closedandthe rear panel I0 of said drawer extends slightly above the upper edgesof the side walls 5.

Slidably mounted in the drawer cell and directly under `the strips 6.arel a pair vof floating 'track rails II.

The floating track rails are 'formed with pockets -in their frontportion for the .reception of pairs which forms a 4drawer supportingarrangement, as best shown in Figures 1 and 3.

. The rear .ends of the floating track rails II are provided with upwardprojections havingmounted therein anti-friction rollers I2", whichrollers are adapted to engage the fixed track rails 4 under certainconditions. l

The rear end of each iioating rail I I' is provided with an upperchannel I 3 and a lower channel I4. The upper channel is engaged by astop pin I5, extending downwardly from the drawer strip 6 and the lowerchannel is similarly engaged by a stop pin I6, which extends upwardlyfrom the drawer supporting wall 3. i i

Under certain conditions it is desirable to bodily remove the .drawerfrom its cabinet cell and with this in View the front ends of the fixedtrack rails 4 are stopped short of the front face of the cabinet, asbest illustrated in Figures 1, 5 and 6,

The spaces between the panel 9 and front ends of said fixed track railsare filled in, at this gap,

by removable stop blocks I1, which blocks carry tongue pieces I1' ingrooved and dove-tail union and locks these associated partsr detail, itis understood that I may vary such details within the scope of theclaims.

I claim:

- l. In a cabinet having side walls and a drawersupporting bottom wall,a drawer havingq side walls and front and rear panels movable in thecabinet; the combination of van extensible support for the drawer,comprising a pair of fixed track rails secured to the side walls of thecabinet, strips secured to the drawer side Walls under the fixed rails,a pair of longitudinally disposed floating track rails, positioned underthe drawer strips and slidably mounted upon the cabinet bottom wall,

` said oating track rails being provided with upblocks I1 aredisconnected from the ends of the track rails 4, by looseningthels'crews '|8, whereby the rear rollers 8 of the drawer strips arefreed from engagement with the said blocks andhen'ce the rear end of thedrawercanfno'w be'tilted np- Wardly as indicated'in Figure 6, :whereby`the pins I5 maybecleared from the floatingrail channel In the operationvofthe cabinet drawer, when the same is pulled out, the initial movementcauses the rollers .1 tofrun voff the front4 endo the track rail lIl.Incidentalqto lthis movement the rollers 1', due tofsaid'conditons, will"act as a fulcr'um, whereby the rear rollers Il reverse the load strain,transferring thesame tothe fixed.

track rail '4 in what mightbe termed a cantilever movement. yWhen thedrawer :reaches approximately one-half of itsopen position, -the stoppin I5, will engage the front end of the channel I3y and thereby pickupthe floating-.track rail II and cause .the 'same to be moved forward, tothe position indicated lindotted lines in Figure-1. In thismovementwhenv the front rollers I 2 ofthe floating track rail, leave thecabinet support lwall 3, the oating rail I I is now fulcrumed 'upon theroller 'I2,and 'willcausethe load strain to be reversed and exertedrupon thefixedtracktby the roller I2, 'associated'with the-floatingIriail, thus developing the same 'cantilever 'movement previouslydescribed'with reference to the-drawer strip rollers 1,1.
